Independently controlled RGB LEDs let the interior and exterior be lit any thousands of colors.

These pics aren't that good. I've since done the compass pod in the middle of the dash (looks so much better) and wired the fogs and nozzle lights to alternate between their current color and orange work with the blinkers.

This has been done and done over a few times. Currently working on revision 3, PIC based, with underlights tied in as well.
